  • Patent number: 10338823
    Abstract: A data storage system can scan one or more information stores of primary storage and analyze the metadata of files stored in the one or more information stores of primary storage to identify multiple, possibly relevant, secondary copy operations that can be performed on the files. The storage system can also identify primary storage usage information of each file during the scan and use that information to generate reports regarding the usage of the primary storage.

  • Publication number: 20190196729
    Abstract: Techniques for providing shared access to, e.g., a small computer system interface (SCSI) storage device in a computer network include providing an operational mode on SCSI interfaces with a first media agent and a second media agent such that, in response to inquiry messages on the SCSI interfaces, the SCSI storage device appears as a SCSI target device to the first media agent and the second media agent and mapping data operations between the first media agent and the SCSI storage device and the second media agent and the SCSI storage device to logically unique channel numbers for the first media agent and the second media agent to perform data storage operations over their respective SCSI interfaces by concurrently sharing the SCSI storage device.

  • Publication number: 20190188188
    Abstract: Techniques for providing data preview before recalling large data files are disclosed. In one aspect, a data file is made accessible while being offline by converting the data file from a native format to a preview format, storing the data file in the preview format in a primary storage that is locally available and moving, after the conversion to the preview format, the data file in the native format to a secondary storage. When a viewing request is received for the data file, the data file in the preview format is displayed to fulfill the viewing request.

  • Publication number: 20190179713
    Abstract: Described in detail herein are systems and methods for single instancing blocks of data in a data storage system. For example, the data storage system may include multiple computing devices (e.g., client computing devices) that store primary data. The data storage system may also include a secondary storage computing device, a single instance database, and one or more storage devices that store copies of the primary data (e.g., secondary copies, tertiary copies, etc.). The secondary storage computing device receives blocks of data from the computing devices and accesses the single instance database to determine whether the blocks of data are unique (meaning that no instances of the blocks of data are stored on the storage devices). If a block of data is unique, the single instance database stores it on a storage device. If not, the secondary storage computing device can avoid storing the block of data on the storage devices.

  • Publication number: 20190179805
    Abstract: Data storage operations, including content-indexing, containerized deduplication, and policy-driven storage, are performed within a cloud environment. The systems support a variety of clients and cloud storage sites that may connect to the system in a cloud environment that requires data transfer over wide area networks, such as the Internet, which may have appreciable latency and/or packet loss, using various network protocols, including HTTP and FTP. Methods are disclosed for content indexing data stored within a cloud environment to facilitate later searching, including collaborative searching. Methods are also disclosed for performing containerized deduplication to reduce the strain on a system namespace, effectuate cost savings, etc. Methods are disclosed for identifying suitable storage locations, including suitable cloud storage sites, for data files subject to a storage policy.

  • Patent number: 10310950
    Abstract: Multiple data paths may be available to a data management system for transferring data between a primary storage device and a secondary storage device. The data management system may be able to gain operational advantages by performing load balancing across the multiple data paths. The system may use application layer characteristics of the data for transferring from a primary storage to a backup storage during data backup operation, and correspondingly from a secondary or backup storage system to a primary storage system during restoration.

  • Patent number: 10296607
    Abstract: A data storage system protects data identified for deletion which has been created or modified between scheduled data backups. For instance, the system monitors data operations and when the data operation is a delete, the system determines whether the data identified for deletion has been protected by a backup operation. Data that has not been backed up, such as newly created data, is copied to temporary storage before deletion. When the data has been protected, the system determines whether the data has been modified after the backup operation. Data modified after the backup operation is copied to temporary storage before deletion.

  • Publication number: 20190146948
    Abstract: An information management system according to certain aspects may determine whether storage operations will work prior to executing them. The system may check various factors or parameters relating to a storage policy to verify whether the storage policy will work at runtime without actually executing the policy. Some examples of factors can include: availability of primary storage devices, availability of secondary storage devices, license availability for performing that operation, user credentials for connecting to primary and/or second storage devices, available storage capacity, connectivity to storage devices, etc. The system may also check whether a particular system configuration is supported in connection with storage operations. The result of the determination can be provided in the form of a report summarizing any problems found with the storage policy. The report can include recommended courses of action or solutions for resolving any identified issues.

  • Publication number: 20190138397
    Abstract: A data protection scheduling system provides a flexible or rolling data protection window that analyzes various criteria to determine an optimal or near optimal time for performing data protection or secondary copy operations. While prior systems may have scheduled backups at an exact time (e.g., 2:00 a.m.), the system described herein dynamically determines when to perform the backups and other data protection storage operations, such as based on network load, CPU load, expected duration of the storage operation, rate of change of user activities, frequency of use of affected computer systems, trends, and so on.

  • Patent number: 10223365
    Abstract: An information management system according to certain aspects may determine whether snapshot operations will work prior to executing them. The system may check various factors or parameters relating to a snapshot storage policy to verify whether the storage policy will work at runtime without actually executing the policy. Some examples of factors can include: availability of primary storage devices for which a snapshot should be obtained, availability of secondary storage devices, license availability for snapshot software, user credentials for connecting to primary and/or second storage devices, available storage capacity, connectivity to storage devices, etc. The system may also check whether a particular system configuration is supported in connection with snapshot operations. The result of the determination can be provided in the form of a report summarizing any problems found with the snapshot storage policy.

  • Patent number: 10191675
    Abstract: A system and method are provided for pooling storage devices in a virtual library for performing a storage operation. A storage management device determines a storage characteristic of a plurality of storage devices with respect to performing a storage operation. Based on a storage characteristic relating to performing the storage operation, the storage management device associates at least two storage devices in a virtual library. The storage management device may continuously monitor the virtual library and detect a change in storage characteristics of the storage devices. When changes in storage characteristics are detected, the storage management device may change associations of the storage device in the virtual library.
